Pal-GHK (Palmitoyl Tripeptide-1)

Pal-GHK is a lipid-modified version of the GHK tripeptide designed for enhanced skin penetration. The palmitoyl group increases lipophilicity. It is a key component of the Matrixyl 3000 complex and stimulates collagen production.

Category: Cosmetic. Evidence rating: D (animal/preclinical only).

Clinical status: Cosmetic ingredient

The palmitoyl group enhances transdermal delivery through the stratum corneum. Once delivered, the GHK moiety activates collagen synthesis and ECM remodeling via TGF-beta pathway activation.

Safety considerations: Well-tolerated topically.
